How to hide form button using IF statement?

vbcoach · May 17, 2016

Hello all.

I have a sports league website that is used for captains to be able to view and manipulate certain items displayed in a form format. I want to be able to hide or disable two buttons in the form; the Edit and Remove buttons based on a simple IF statement. However I am not quite being able to make this happen, as the form is outside of the PHP statement.

<body> 

<table width="800" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td><img src="images/BBV_CP_top.jpg" width="800" height="200"></td>
  </tr>
  <tr>
    <td><table width="100%"  border="0" cellspacing="0" cellpadding="2">
      <tr>
        <td width="6%" class="menu"><a href="home.php"> Home</a> </td>
        <td width="9%" class="menu">
		<?php if  {echo "<a href=editTeam.php> Edit Team </a>";}?></td>
        <td width="12%" class="menu">
        <?php if ($team[session] == 'Summer') {echo "<a href=addPlayer.php> Add Player </a>";}?></td>
        <td width="63%" class="menu"><br>
		<?php if ($team[session] == 'Summer') {echo "<a href=editInfo.php> Edit My Information </a>";}?></td>
        <td width="10%" class="menu"><a href="logout.php">Log Out </a></td>
      </tr>
    </table></td>
  </tr>
  <tr>
    <td><table width="765"  border="0" cellspacing="1" cellpadding="1">
      <?php  if($info['feepaid'] == 'n')

Under the Players table, there is an Edit and Remove button. I would like to hide this button based upon a PHP statement that looks a bit like this: <?php if ($team[session] == 'Summer')... Basically we are in the Spring session, thus at this point in the season, I do not want teams to be able to edit, add, or remove any player information. However the same database is used for both Spring and Summer registrations.

So any help incorporating this php statement to hide these buttons would be greatly appreciated! -J

Well, if you are using sessions, it is easy. Just put

$_SESSION['season'] = 'Summer'

or

$_SESSION['season'] = 'Spring'

in the header of the your application and then use the if statements to check the value of the $_SESSION variable. If you don't want to manually update the value of the season session, you can put it inside a switch statement

You haven't posted anything about your database which is really where this starts. You should have a db column is_summer with a one or zero. Then in your code

if (row['is_summer']){
// button code
}

He said he can't modify the DB.

To the OP -> Remove the inline stylings. Use CSS. It will be a pain to modify the code later on.

He said he can't modify the DB.

Really? Where does it say that?

Let me try this again. In the middle of my page, there is a form statement that creates buttons to push. I would like to create an "IF" statement to display or not display these buttons. In my code I use "session" but it really means "season" as in Spring or Summer. So if the "season" = Summer, then display these buttons. The basic code for these buttons looks like this:

               <?php
			if($row['ptsordered'] == '')
			{
			?>
                  <form name="player<?= $row['p_id'] ?>" action="editPlayer.php" method="get">
                  <input type="hidden" name="p" value="<?= $row['p_id'] ?>">
                  <input name="Submit" type="submit" class="button" value="Edit">
              </form>
            <?php
			}
			?>
            </td>
      
             <td><form name="del_player<?= $row['p_id'] ?>" action="remPlayer.php" method="post" onSubmit="return(confirm('Are you sure you want to delete <?= $row['name']?>?\n\nThis cannot be reversed'))">
                  <input type="hidden" name="p" value="<?= $row['p_id'] ?>">
                  <input type="hidden" name="t" value="<?= $id ?>">                  
                  <input name="Submit" type="submit" class="button" value="Remove">
              </form></td>
            </tr>
            <?php $i++; } ?>

So I need help with a PHP statement that says if "session = 'Summer" then ..." displays the buttons, if not, the buttons are not displayed. Does this make sense now? Sorry for the confusion.
